* specify the desired bit depths of the various components of the default
* framebuffer.
*

* in Hz, of the video mode for a fullscreen window, or zero to let the system
* choose a suitable refresh rate. If a windowed mode window is created, this
* hint is ignored.
*
* The @ref GLFW_ACCUM_RED_BITS, @ref GLFW_ACCUM_GREEN_BITS, @ref

*
* For OpenGL, these hints are @em not hard constraints, as they don't have to
* match exactly, but @ref glfwCreateWindow will still fail if the resulting
* OpenGL version is less than the one requested. It is therefore perfectly
* safe to use the default of version 1.0 for legacy code and you will still
* get backwards-compatible contexts of version 3.0 and above when available.
*
* For OpenGL ES, these hints are hard constraints, as there is no backward
* compatibility between OpenGL ES versions.
*
* If an OpenGL context is requested, the @ref GLFW_OPENGL_FORWARD_COMPAT hint
* specifies whether the OpenGL context should be forward-compatible, i.e. one
* where all functionality deprecated in the requested version of OpenGL is
* removed. This may only be used if the requested OpenGL version is 3.0 or
* above. If another client API is requested, this hint is ignored.
*
* If an OpenGL context is requested, the @ref GLFW_OPENGL_DEBUG_CONTEXT hint
* specifies whether to create a debug OpenGL context, which may have
* additional error and performance issue reporting functionality. If another
* client API is requested, this hint is ignored.
*
* If an OpenGL context is requested, the @ref GLFW_OPENGL_PROFILE hint
* specifies which OpenGL profile to create the context for. Possible values
* are @ref GLFW_OPENGL_NO_PROFILE, @ref GLFW_OPENGL_CORE_PROFILE and @ref
